which statement is true about ionic compounds?
they are made up of many large molecules that are bonded together.
they are made up of atoms of only one type of element.
they are made up of particles that are arranged in a repeating pattern.
they are made up of a random ratio of elements that are bonded together.

Explanation:

Ionic compounds form crystalline structures with a repeating, ordered lattice of ions, not discrete large molecules. They consist of at least two different elements (a cation and anion) in a fixed, non-random ratio, eliminating the other incorrect options.

Answer:

They are made up of particles that are arranged in a repeating pattern.
